The primary objective of aggregating the impact of IT risk scenarios and reflecting the results in the enterprise risk register is to ensure IT risk impact can be compared to the IT risk appetite, as it enables the organization to measure and evaluate the overall level and exposure of the IT risk, and to align and prioritize the IT risk response and strategy with the organizational objectives and regulations. The other options are not the primary objectives, as they are more related to the communication, assignment, or assessment of the IT risk scenarios, respectively, rather than the aggregation or reflection of the IT risk scenarios.
